Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
Answer:
(1,3) should be the answer due to the fact that both lines intersect at that point.
Step-by-step explanation:
I’m guessing you just have to multiply all the sides together and divide
If you times it by 100 you would have to move the decimal point right two steps.
If you multiply a decimal with 10 you would move the decimal point once to the right. if you had 1000 you would have to move the decimal point three times to the right because there are three zeros.

Answer: he would need 77 scoops of fertilizer.
Step-by-step explanation:
The measure of Horalco's garden is
10 1/2 ft by 5 1/2 ft. Converting to improper fraction, it becomes 21/2 ft by 11/2 ft. The garden is rectangular in shape and the formula for determining the area of a rectangle is expressed as
Area = length × width.
Therefore, area of the garden is
21/2 × 11/2 = 231/4 ft²
He needs 1 1/3 scoops of fertilizer for each square foot of the garden. Converting to improper fraction, it becomes 4/3 scoops. Therefore, the number of scoops of fertilizer that Horaclo need for the entire garden is
4/3 × 231/4 = 77 scoops of fertilizer.
